Tripower L71 Maintenance Tips
1969 Corvette 427/435. I’m a new owner… Not too mechanically inclined;
What are some of the L71 “must” maintenance tips to keep the engine running the best it can?
I’ll have someone else do the work, but want to keep on a good routine and schedule.
It’s an original engine. 88,000 miles. Auto.

THE #1 thing is to start it and drive it periodically. If you leave gas in those carbs for longer than 2-3 months you will regret it....especially on a Tri-Power. Getting heat in the engine, trans and rearend prevents moisture from building up.
Other than that.....follow the Factory Manual for Maintenance Intervals.....plugs, points, oil change...etc.

L-71's are not particularly pump gas friendly...they have an 11 to 1 compression......verify that you do not need more octane than premium pump fuel......listen for spark knock......if you have spark knock, an octane additive may be mandatory to drive it often. If you feel a large increse in performance with the booster....you are on the right track. Any 100 octane pump "race" fuel is fine too but pricey.
